This is actually a vey important study. The truth is that physicians have become very skeptical of the use of hugely expensive procedures and medications. The studies that are published in medical journals are themselves often sponsored by the companies that make medications or the equipment used in the procedures. The medical journals themselves are full of advertisements from those same companies.
When it comes to heart attack, nothing but nothing has more effect diminishing the incidence and severity of heart attacks than preventing and discontinuing cigarette smoking. No mammal evolved with the capacity to deal with chronic elevated blood levels of carbon monoxide. After that its the use of aspirin , beta blockers and blood pressure control. Perhaps, just perhaps the use of statins has been beneficial in some.
Its good to be a bit skeptical and reflect why the herd advocates and uses all these expensive drugs and procedures.
